A LAWYER for R&B star Ray J has slammed Bobby Brown's sister for suggesting he is withholding information about Whitney Houston's death.

The music icon was found submerged in the bathtub of her Los Angeles hotel suite on February 11. On Thursday, her cause of death was officially ruled as accidental drowning, in addition to the effects of heart disease and years of cocaine use.

The singer's former sister-in- law, Leolah Brown, appeared on talk show Dr Drew on Thursday to discuss her version of events leading up to the superstar's passing. In the interview, she accused Ray J of helping Houston to indulge in her addictions, since he allegedly "knows somebody that sells drugs".

Recounting the night of the legend's death, Brown said: "I saw Ray J coming out of the hotel, hiding his head, being pushed into a car. Why? I looked and I said, 'Why is he hiding his face? He's always trying to show his face around Whitney. Why now? Why are you trying to hide, Ray J?'"

However, a representative for Houston's on/off boyfriend Ray J has lashed out at the claims.

The star's attorney says: "Though Leolah Brown was nowhere near the Beverly Hilton Hotel on the day Whitney Houston died, [TV network] CNN proceeded to broadcast an interview in which she falsely claimed that Ray J was at the hotel and contributed to Houston's death. Leolah Brown had been out of contact with Whitney for more than a year."
